there is political will among the nation's that are prepared to be involved. it also requires the consent -- we have to imagine this -- the consent of the libyan people. if you bring down a libyan jet, that is an act of war. you have to be very careful. cannot just say, we're not operating on the ground, bring down a jet on to libyan soil, and it is an act of war. >> that could bring about greater military involvement, which is not necessarily what powers like britain and the united states are looking for. >> not only that, we cannot do it. the british are stretched enough as it is, and so are the united states. let's just ask -- who else could actually help here? let's see the arab world to think about what they might do. the trouble is, a lot of the arab world have got dictatorships as well. they are extremely worried. this is an extremely worrying development.
